My own skid of BleachHack for 1.19.2 I made this to make Bleach compatible with meteor and even gone so far as changing prefix to + and ClickGui bind to right control
I also gave it own visual flavour

Download Fabric for Minecraft 1.19.2. Download the latest version of DarkHack for your Minecraft version from releases.

On Windows: Type %appdata% into the Windows search bar; open the folder that comes up and then open '.minecraft'.

On Mac: Click on the desktop, press Command+Shift+G, type ~/Library and press enter; then open 'Application Support' and finally '.minecraft'.

On Linux: in a terminal window, type 'xdg-open ~/.minecraft'... or if you like working at the commandline, 'cd ~/.minecraft'.

Then inside that folder, you should see a folder named 'mods'. (If you don't see one, make sure you've installed Fabric already and started Minecraft again once). That's where you'll put any mods you want to install.

Download the branch with the version you want to work on.
Start A Command Prompt/Terminal in the main folder.
Generate the needed files for your preferred IDE.
